JP7550451B2 - Translucent cosmetic material with radiance - Google Patents

Description

The present invention relates to a translucent cosmetic product with a radiant glow. According to the present invention, it is possible to provide a cosmetic product with a radiant glow.

Cosmetics are expected to have functional effects such as maintaining the beauty of the skin and improving the condition of the skin, as well as effects such as the beauty and interest of the appearance of the cosmetic itself. For example, a multi-layer cosmetic is a cosmetic that combines the functional effect of preventing the deterioration of ingredients due to layer separation, as well as the beauty and interest of the appearance of the cosmetic due to the formation of layers (Patent Document 1).

JP 2019-147758 A

It is important for cosmetics to have functional effects. However, in addition to functional effects, it is also important that the cosmetic itself has an interesting or beautiful appearance that lifts the spirits of those who use the cosmetic. Therefore, the object of the present invention is to provide a cosmetic that has the basic functional aspects of a cosmetic and also has a beautiful or interesting appearance.

The present inventors have conducted intensive research into cosmetics that have the basic functional aspects of cosmetics while also exhibiting beautiful or interesting appearances, and as a result have surprisingly discovered that a translucent cosmetic composition containing a specific hydrophilic surfactant, a lipophilic surfactant, and an oily component exhibits a beautiful radiance.
The present invention is based on these findings.
Thus, the present invention provides
[1] (A) a polyoxyethylene polyoxypropylene alkyl ether represented by the following formula (1): RO-[(C ₂ H ₄ O) m (C ₃ H ₆ O) n]-H (R is a branched alkyl group having 10 to 40 carbon atoms, m is an integer from 10 to 40, and n is an integer from 2 to 30), (B) a lipophilic surfactant selected from the group consisting of sorbitan difatty acid, sorbitan sesquifatty acid, glyceryl difatty acid, glyceryl sesquifatty acid, polyglyceryl difatty acid, and polyglyceryl sesquifatty acid, each of which has a fatty acid of 16 to 20 carbon atoms, and (C) an oily component,
A translucent cosmetic having a radiance,
[2] The translucent cosmetic composition having luster according to [1], further comprising (D) a liquid higher fatty acid or a liquid aliphatic alcohol.
[3] (E) A translucent cosmetic composition having luster according to [1] or [2], further comprising a solid higher alcohol or sterol; and [4] (F) A translucent cosmetic composition having luster according to any one of [1] to [3], further comprising an anionic surfactant.
Regarding.

The cosmetic of the present invention allows the translucent cosmetic itself to exhibit a beautiful radiance. The cosmetic of the present invention can contain solid higher alcohols, cholesterol, and phytosterols that were previously added using high-pressure emulsification methods, without using high-pressure emulsification. The transparency of the cosmetic of the present invention can be improved by including liquid fatty acids, liquid fatty alcohols, or anionic surfactants.

Action
The reason why the cosmetic material of the present invention exhibits a beautiful radiance has not been completely elucidated, but can be presumed as follows. However, the present invention is not limited to the following explanation.
The cosmetic of the present invention contains polyoxyethylene polyoxypropylene alkyl ether (component A), a fatty acid sorbitan having 16 to 20 carbon atoms, a fatty acid glyceryl, or a fatty acid polyglyceryl (component B), and an oily component (component C). It is presumed that by containing components A, B, and C, these three components form liquid crystals, and that this liquid crystal is finely dispersed in the liquid, reflecting light and exhibiting iridescence.
The cosmetic of the present invention can contain ingredients that maintain the beauty of the skin and improve the condition of the skin while maintaining the effects of the present invention. Therefore, it is possible to provide a cosmetic that has the basic functional aspects of a cosmetic and also has the beauty or interest of its appearance.

The present invention will be described in detail below with reference to examples, but these are not intended to limit the scope of the present invention.

Examples 1 to 8
In this example, polyoxyethylene polyoxypropylene decyl tetradecyl ether (RO-[(C ₂ H ₄ O) ₂₄ (C ₃ H ₆ O) ₁₃ ]-H; R is decyltetradecyl) was used as component A, and sorbitan sesquiisostearate or polyglyceryl-2 diisostearate was used as component B. They were mixed in the composition of the oily components and the like shown in Table 1 to prepare a cosmetic preparation. The mixing was performed by mixing composition (1), followed by the sequential addition of composition (2) and composition (3).
The L value and the presence or absence of radiance are shown in Table 1. Figure 1 shows photographs of Examples 1 to 3, and a comparative example that does not contain Component B. The cosmetic preparation that does not contain Component B did not exhibit radiance, but the cosmetics of Examples 1 to 3 exhibited beautiful radiance. As shown in Table 1, the cosmetics of Examples 1 to 8 exhibited excellent L values and excellent radiance. The L value was measured as follows.
Using an SM color meter (SM-T, manufactured by Suga Test Instruments Co., Ltd.), 5 mL of purified water was placed in a glass cell, and the transparency was measured by setting the transparency when light was transmitted through the cell at 100 and the transparency when light was completely blocked and no light was transmitted at 0.

Examples 9 to 17
In this example, polyoxyethylene polyoxypropylene decyl tetradecyl ether (RO-[(C ₂ H ₄ O) ₂₄ (C ₃ H ₆ O) ₁₃ ]-H; R is decyltetradecyl) was used as component A, polyglyceryl-2 diisostearate was used as component B, and they were mixed according to the composition of the oily components and the like shown in Table 2 to prepare a cosmetic preparation. The mixing was performed by mixing composition (1), followed by the sequential addition of composition (2) and composition (3).
The L value and the presence or absence of radiance are shown in Table 2. As shown in Table 2, the cosmetics of Examples 9 to 17 exhibited excellent L values and excellent radiance.

In this example, polyoxyethylene polyoxypropylene decyl tetradecyl ether (RO-[(C ₂ H ₄ O) ₂₄ (C ₃ H ₆ O) ₁₃ ]-H; R is decyltetradecyl) was used as component A, and polyglyceryl-2 diisostearate was used as component B. They were mixed in the composition of the oily components and the like shown in Table 2 to prepare a cosmetic preparation. That is, the ratio of components A and B was changed to study the sense of brilliance. The mixing was performed by mixing composition (1), and then adding composition (2) and composition (3) in that order.
The L value and the presence or absence of radiance are shown in Table 3. In addition, "skin compatibility" and "non-stickiness" were evaluated by a panel of 12 female members and were recorded with the following "good", "good", or "bad".
Skin compatibility: ◯: 9 or more panelists rated it as good skin compatibility △: 4 to 8 panelists rated it as good skin compatibility ×: 3 or less panelists rated it as good skin compatibility Non-stickiness: ◯: 9 or more panelists rated it as not sticky when applied to the skin and good spreadability △: 4 to 8 panelists rated it as not sticky when applied to the skin and good spreadability ×: 3 or less panelists rated it as not sticky when applied to the skin and good spreadability As shown in Table 3, the cosmetics of Examples 18 to 24 exhibited excellent L values and excellent radiance. Furthermore, when the amount of Component B was small, the "skin compatibility" and "non-stickiness" were slightly decreased, but the radiance was excellent.

Examples 23 to 31
In this example, the effects of the fatty acid (isostearic acid) or fatty alcohol (isostearyl alcohol) of component D and the anionic surfactant of component F were investigated. Cosmetics were prepared by mixing the components in the compositions shown in Table 4.
